Setup syn54x Skills

Scaffold the per-repo configuration that the engineering skills assume:

• Issue tracker: where issues live (GitHub by default; local markdown is also supported out of the box)

• Domain docs: where CONTEXT.md and ADRs live, and the consumer rules for reading them
• SDD pipeline (GitHub only, optional): labels, issue types, the routing block, and the cloud workflows the spec-driven build skills assume
